Kepler-372 and Its Three Worlds

Kepler-372 is a star located 4870 light-years away. It is 3.09 billion years old and has a mass of 1.12 solar masses, a radius of 1.18 solar radii, and a temperature of 6150 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. Three planets orbit this host.

All three planets were discovered in 2014 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish orbital periods.

Kepler-372 b is an Earth-like planet with a radius of 1.36 Earth radii and an orbital period of 6.85 days. Among the listed planets, it has the shortest year and the smallest radius by reported estimates.

Kepler-372 c is a Super-Earth with a radius of 2.09 Earth radii and an orbital period of 20.1 days. Its reported radius estimate is larger than Earth's. Among the listed planets, it has the second-shortest year and the largest radius by reported estimates.

Kepler-372 d is a Super-Earth with a radius of 1.69 Earth radii and an orbital period of 30.1 days. Among the listed planets, it has the longest year and the second-smallest radius by reported estimates.
